Chapter VI Troubleshooting
Please refer to the list below if you encounter any problems when
using your phone. If you tried but the problem has not been solved,
contact a qualified Meridian Mobile dealer or your local maintenance
center immediately.
■Your display prompts Enter PIN Code:
Enter the valid PIN code for your SIM card. If you do not know this
code, contact your network service operator immediately.
■Your display prompts Enter PUK Code:
If you enter the PIN code incorrectly three times in a row, your SIM
card will be locked. In this case, you have to enter the PUK code to
unlock your SIM card. Please contact your network service operator
immediately.
■Your phone prompts Insert SIM card
Make sure that your SIM card is correctly installed. Check whether
your SIM card works normally. This message may indicate that your
SIM card is defective or damaged. In this case, contact your network
service operator.
■Your phone prompts Out of Service Area or Network Failure:
Check your signal strength indicator. If the indicator shows no signal,
you may be in a basement or a building corner not covered by your
wireless network. Move to another location where the signal is strong
enough. There is another possibility: you may be in an area not
covered by your wireless network. You may ask your network service
operator to inform you of the network coverage.
■The sound is of poor quality, or there is echo or noise, making it
difficult to call:
Hang up the call, and dial again. Your network service operator may
provide you with a better link when you retry.
